Abstract
The corrosion and kinetics of partial electrode reactions on St3 carbon steel with a superhydrophobic coating based on methoxy fluorobutylsilane derivatives in 0.5 M NaCl solution were studied. This influence of in situ duration τ of the medium’s corrosive action (0.5–144 h) on its protective effect is considered. This allows reduction of overall corrosion rate by 23 ± 3 times, when the stationary state is reached. The kinetics of cathodic reduction of dissolved oxygen and steel anodic ionization is also considered. In the initial stages of corrosive action of neutral aerated chloride medium (until steady-state characteristics are reached), steel at potential E near Ecor corrodes in the active state, whereas, when τ is ≤0.5 h, it corrodes under anodic control conditions, and then the control is replaced with a cathodic one.
